You're being actively recruited into a doomsday cult. The recruitment period into a cult can be likened to a "honeymoon" phase. The group's members will make you feel welcomed and accepted; they've been trained to act this way. You really should read as much as you can about cults and cult recruitment tactics. Combatting Cult Mind Control by Steve Hassan is a great book that will give insight into what you'll be experiencing if you continue allowing the Watchtower recruiters to pull you into their isolated little world.
The Watchtower representatives will claim they're not trying to recruit you, that they only want to share teachings from the Bible with you, that's a lie. The structure of the door to door work is designed to make people become members. You will be taught that only the group has "truth". You'll eventually be told to isolate yourself from those outside the group because they're in the "world" and bad association. You'll eventually be told that only people inside the group will survive an impending judgment from God. They'll eventually tell you that this judgment day is coming soon, and you must go door to door recruiting new members in order to earn your way into paradise.

Please for your own sake as well as your loved ones (cults often require that loved ones must be recruited as well) research as much as you can about the Watchtower organization. jwfacts.com is fantastic resource for anyone wanting to learn what the Jehovah's Witnesses really teach.

Most Jehovah's Witnesses are decent people; it's a misconception to think that someone in a religious cult is a bad person or somehow unintelligent. Most of the members were born into the group, they can't escape unless they're willing to lose their family and "friends" still in the group. After recruitment into the group there is no way to honorably leave, those who try to walk away peacefully are slandered as being influenced by Satan or gross sinners. Maintaining a relationship with someone who walks away from the group is forbidden, even family members. The group will become your new family; the group members will become your new brothers and sisters. But this sense of family and belonging will be removed the instant you question the leadership of the group. Anyone that doesn't show complete obedience to the group and the unique doctrines of the group are judged as being bad association and undeserving of God's protection at Armageddon.
Eventually you'll be taught that the men who run the religion have been chosen by God, and to question these men is equivalent to questioning God himself. These men on the Governing Body who run the religion get to decide what's "truth" and how the Bible should be interpreted. Disagreeing with these imperfect men and their interpretation of scripture will get you disfellowshipped. As a new recruit into the group you're free to ask as many questions as you want, once fully recruited into the group this freedom is stripped from you. After the recruitment process, openly questioning the leaders of the group will get you marked by other obedient members as "spiritually weak", and you'll be threatened with expulsion.
Take your time and fully research this apocalyptic group. The rabbit hole goes very, very deep.
